Glasgow-Blatchford vs ABC score to identify low risk patients by Upper Gastrointestinal Bleeding patients: a prospective multicentre cohort study

Aims Guidelines suggest using the Glasgow-Blatchford (GB) score to triage bleeding patients needing hospital admission. However, no data compared the predictive value of GB vs. other scores (Rockall, AIMS65, PNED, and ABC). We aimed at comparing their prognostic performance in identify the very low-risk patients for mortality by upper gastrointestinal bleeding (UGIB)
